Answer:
The equation of the line is 
Step-by-step explanation:
Equation of a line:
The equation of line, in point-slope form, is given by:

In which m is the slope and the point is 
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Through (9,-7)
This means that 
So



Perpendicular to y = 3x + 4
This line has slope 3, so:


Thus


Are you asking for the x of those two problems?
